How many rounds will Pac-Clottey go?

I just laid down 300 big ones at -175 that this fight goes past 1:30 of the 10th round. That makes the over/under 9.5. I see this fight going like this: Pacquiao jumps in and out throwing alot of combos, as always. Some might get through the earmuffs and drive Clottey back in the first half of the fight. Toward the second half, after Pac slows slightly, Clottey will land a few good counters and lead rights. The first half will be a Pac shutout, the second half a split(3 rds. each) Pacquiao wins an easy decision 117-111 but it will be entertaining, although no one is going to be close to hurt in the fight. How many rounds do you see it going?
